It will need to be replaced, which is not too hard and not too expensive. Use the search tool to find the directions.

The gas heating element is controlled by the switch on the front apron of the kitchen sink. The red light indicates that it is trying to light the gas flame (it lights automatically) but hasn't yet succeeded. If the gas was turned off at the tanks, that is the reason.

Neither heater should be activated when there is no water in the heater.
